No need for apologies, it's just that its incredibly difficult to explain positioning of soccer positions with any degree of haste. There are general guidelines, but there are far too many aspects that can change those guidelines. There are also several different formations that are used in soccer....akin to the differences in the 4-3 and the 3-4 defenses in football. Sometimes teams play with 1 striker, sometimes 3. Each formation changes the responsibilities of each particular forward.
The fact that a forward players responsibilities overlap with other forward players is compounded by the fact that they also overlap with the responsibilities of midfielders. Lots of overlapping.
A layperson's view of the sport is very different from a player's view, that's for sure.
